Voice Controlled Home Automation Design

Abstract

In recent years, in parallelwith the advances in technology, home automation systems have started to offermore functions and been more sophisticated. Compared to the past, remotelycontrollable home automation systems have become much cheaper and are notluxurious anymore; hence more and more people nowadays use home automationsystems to make their lives easier. Home automation systems especially play akey role for the elderly and disabled and offer convenient and flexiblesolutions for them. Since home automation systems allow the elderly andphysically disabled to maintain their lives in a comfortable and secureenvironment, the aim of this study is to design a voice controlled homeautomation system. To design the proposed home automation system, firstly aprototype home has been built and then some devices have been placed in it.Then, by using a throat microphone, a set of voice commands has been defined inthe voice recognition module. The designed home automation system works asfollows. Basically the voice recognition module converts voice commands intodigital signals, and then these digital signals are transmitted to the homeautomation system via a ZigBee-based communications module. The receiver of theZigBee communications module receives the commands given by the transmitter andsends them to the microcontroller. Finally, the microcontroller analyzes thecommands and performs the expected operations. Arduino Uno has been used as themicrocontroller and EasyVR module has been used for voice recognition. Thesoftware of the home automation system has been developed in C using Arduino IDE.
